' 6 Claims. (or. 241-1005 j This application is a division of patent application Serial No. 392,873, filed November 18, 1953. cut application is a continuation of an application filed "December 20, 1951, Serial No. 262,626, now abandoned.

The parfofthe type described which is exceedingly easy to install.

In most instances it has been necessary in the mounting of disposers in the past for the installer to hold the unit in place while bolts and other attaching devices are put in place and secured. This is. diflicult and awkward to do, working in the cramped quarters of the cabinet structure under the average sink. The present invention provides a means whereby the unit may be quickly and easily initially suspended from the drain sleeve of the sink, which places all of the weight of the unit on the drainfsleeve. Thereafter during the installation it is not necessary for the installer to lift or to hold the unit and he has both hands free to complete the installation.

Other objectives and advantages of the invention will .be readily apparent to those skilled in the art from the following detailed description of the drawings in which:

Figure 1 is a view showing the upper portion only of a ,garbage disposer unit with parts being broken away to illustrate the details of a preferred form of the mount- Cing ring of this invention.

Figure 2 is a cross sectional view taken on the line 2-2 of Figure 1 further illustrating the construction of the mounting ring.

Figure 3 is a fragmentary cross sectional view taken on the line 33 of Figure 2.

Figure 4 is a fragmentary view taken on the same plane of Figure 2 showing that portion of the mounting ring illustrated in Figure 3.

Figure 5 is a cross sectional view similar to Figure 3 in which the mounting ring is in unit suspending position prior to being tightened to lock the unit in place beneath a sink.

The details of construction of the garbage disposer unit not illustrated here are shown in the parent application Serial No. 392,873, filed November 18, 1953. In general the unit is enclosed within two upper and lower shells designated 28 and 33 respectively. The upper shell encloses a casing 80 which defines the comminuting chamber of the unit. The casing is generally in the shape of a frustum of a cone and the upper end of the casing is turned in and then up to provide a right angular rim, the rim including an annular shoulder 82 which is generally in a horizontal plane and an upstanding flange 83 which is generally vertical. As disclosed in copending patent application Serial No. 815,991, filed May 26, 1959, also "a' division of the parent application, the upper shell 28 Unit d statfis Pat 2,965,319 Patented Dec. 20, 1960 is locked to the lower shell 33by means of a snap ring In assembly, the concavity is straightened out by forcing the shoulder down into the configuration illustrated here. This lowers the bottom edge of shell 28 into a position where it can be engaged bysnap ring 156. The distortion of the shoulder during assembly does not exceed the elastic limit of the material of which the upper shell 28 is formed, thus the upper shell is under tension, the eflect of which isfto place -a downward force ,upon the annular shoulder 82 at the upper end of thecasing and thus lock the casing in place within the unit.

In general, the mounting ring assembly of this invention consists of a clamp ring 108, a mounting ring l09, and a vibration dampening annulus 110. The purpose of; the mounting ring assembly is to fasten the unit toa 'sink'sleeve which is indicated at 111. The sink sleeve seats in and depends through the drain opening in the Isink. Anoutwardly turned flange 112 at the upper end of the sink sleeve rests upon a gasket 113 which seats on the sink surrounding the drain opening. Below the sink the sleeve is threaded externally as at 114. The inside of the sleeve may be plain as shown. The sleeve may receive a stopper of the type shown at 115, this stopper being fully described in my copending application Serial No. 308,263, filed September 6, 1952, now Patent No.

2,709,046. Mounting ring 109 has a depending inner flange 116 which is threadedly internally to engage the threads on the sink sleeve. The mounting ring has an outer flange 117 turned down from the upper portion 118 thereof to define with inner flange 116 an annular groovewhich opens downwardly to receive the vibration dampening annulus 110. It is preferred that annulus be molded from one piece of rubber or other resilient material andthat it include baflle fingers such as those shown at 119. The underside of annulus 110 has a circular slot 120 formed in it to accommodate the upstanding flange .83 formed at the top of the casing or inner cone 80. In addition to this, the annulus includes a substantially deep,

narrowannular pocket 121 which receives the upper endwise portion of the upper housing shell 28. The upper end of the shell is configurated to provide anupstanding circular flangepthe upper end 122 of which is flared outwardly at substantially 45 as shown in Figures 1, 3 and 5. The pocket 121 conforms to the shape of the flange.

It will be noted that the upstanding flange 122 extends upwardly from an annular shoulder 123 which in the assembled unit lies in a substantially horizontal plane. A circular, resilient gasket 124 seats on the annular shoulder -82 at the upper end of casing 80 surrounding the flange flared clamp ring. Although 'the clamp ring may be molded directly to the rubber annulus, it. is preferred for production reasons to assemble them and to provide, for holding the clamp ring 108 in place, a large band 125 made of rubber or similar material, which surrounds the annulus below the clamp ring to hold it in place, as shown in Figure 'l. Cement may be used to secure band 125 to the annnlus if desired.

In the preferred embodiment, three radially disposed mounting screws 126 are threadedly engaged through the outer flange 117 of themounting ring at equally spaced ints circumferentially thereof. The inner end of each mt itinting screw is founded as shown at 127 and is-d'ebeing pressed tightly against the underside of the mounting ring, serve to seal the joint between the annulus and i the mounting ring. In making an installation, the three mounting ring screws are first backed olf to a point where the mounting Qring 108 can be removed from the unit. The mounting,

ring is then threaded onto the sink sleeve, gaskets such .as those indicated at 130 being used to seal. the space between the bottom of the sink and the upper face of the mounting ring. Slots, such as those indicated at 131,

may be provided in the bottom rim of the sleeve and a m1 inserted in them to prevent the sink'sleeve from turning relative to the mounting ring when the ring is .being tightened into place. Referring now to Figure 2, the outer marginal rim-area of the clamp ring is notched at three places which are spaced to conform to the positions of the respective mounting screws. Each of the notches is indicated by 132. These notches are designed to clear the inner, rounded ends of the mounting screws when they are run in to a point where they would not otherwise clear the edge of the clamp ring. This relationship is illustrated in Figure 2, and it permits the unit to be lifted and engaged in the annular groove in the clamp ring when the screws are run in to the points shown. Once the unit is thus engaged in the groove, it may be ,turned to misalign the notches 132 with respect to the inner ends 127 of the mounting ring screws. This is illustrated in Figure 4. After the unit has been turned, it will hang in place on the mounting ring assembly. This relieves the person making the installation of the burden ,of holding the unit while the mounting ring screws are completely tightened. With the unit thus suspended, the screws can be tightened to a point in which the inner ends thereof are in beyond the notches 132 but not so far in as to clamp the unit in place. Under these conditions, the unit may be rotated without fear of having it .fall from the mounting ring assembly, so that it may be adjusted to properly align the drain outlet 133 with the drain pipe 134. After the drain has been connected, the mounting ring screws may be tightened to securely clamp the unit in place as shown in Figure 1. At no time it is necessary for the workman to hold the unit for any great length of time, and he may use both hands to initially raise the unit to move the notches 132 past the screws. After the unit has been rotated slightly so that the notches are misaligned with respect to the screws, the installer has both hands free to complete the tightening of the screws and to adjust the position of the unit properly with respect to the drain pipe.

Inasmuch as the unit moves slightly during the final tightening of the screws, it is preferred that a resilient .gasket be employed between the drain-outlet of the unit and the fitting by which it is attached to the drain pipe.
